A university football coach has launched a heartfelt social media campaign to locate his daughter, who remains among 10 campers still missing following catastrophic flooding in Texas that has claimed at least 80 lives.

Wade Lytal, offensive coordinator at Division III Trinity University in San Antonio, took to social media platform X with an emotional plea.

"Asking for all prayers for a miracle for my baby girl Kellyanne," he wrote.

The coach shared a video of Kellyanne performing a solo at her primary school's Christmas recital. "I'll never forget when she told me she had a lead solo in the Christmas Pageant," Wade Lytal posted. "She is absolutely fearless."

Trinity University confirmed in a statement that Kellyanne Lytal remains unaccounted for after the devastating flooding along the Guadalupe River.

The young girl vanished from Camp Mystic, a Christian summer camp for girls that bore the brunt of the weekend's devastating floods. Floodwaters obliterated the camp's cabin and swept numerous children and counsellors away.

Five girls from the camp are confirmed dead, along with the facility's owner, Dick Eastland. The catastrophe struck Central Texas with particular severity over the weekend.
